Hi need help please. I have a 2002 Galaxy with the remote not working. I have tried the programme method ( unlock car turn key to unlock 3 times in 5 seconds ) but will not enter programme mode. Can anyone help where am i going wrong. LED on door flashes on door when locked so i know that works. Will not flash when try to programme the key.

Hi I'm new to site. I of my galaxy about a week now. I noticed that when has been sat over night it sometimes takes ages to change gear. I got in it this morning and set of and it didn't change gear at all. It was going up to 3000 rpm. After about approx 10-20 mins it started working. Any ideas please. Thank you.
